After checking an elderly couple, the doctor told them they were physically fine but should consider writing things down to help with their memory.
The couple thanked the doctor and went home.
A few days later, while watching TV, the old man got up from his chair.
His wife asked where he was going.
He replied that he was going to the kitchen.
She asked him to bring her a bowl of ice cream.
He agreed.
She then told him to write it down so he would not forget, but he refused, saying he could remember it.
She added that she would like strawberries on top and again told him to write it down.
He insisted he could remember.
Finally, she said she also wanted whipped cream on top and warned him he would forget.
Irritated, he said he could remember everything and went to the kitchen.
Twenty minutes later, he returned with a plate of bacon and eggs.
His wife looked at the plate and shouted, “You forgot the onions!”
